COMBINATION JACK AND HOIST.

Application led February 8, 1922.

able others skilled in the art to which it ap* pertains to make and usethe same, reference being had to the accompanying drawings, and tocharacters of reference marked thereon, which form a part-of thisspecification.

This invention relates, generally, to improvements in combined liftingjacks and hoists; and, the present invention has reference, moreparticularly, to a novel combina! tion jack and hoist for use especiallywith automobiles which is simple in its construction and is effective,both for lifting the axle and wheel of a vehicle for a. change of tires.or for drawing or pulling` the vehicle out of the sand or mire when thewheels have become imbedded in a manner, that the wheels when operatedwill not grip, and will cause a possible loss, due tobattery-exhaustion, strain upon the engine, or wear and tear upon thetires.

The present invention has for its principal objects to provide a noveland simply constructed combination jack and hoist of the generalcharacter hereinafter more particularly set forth and for the purposesherein-before stated, which is most simple in its construction, ispositive in its action, and is adapted for use either as a jack forlifting purposes, or as a hoistfor pulling the vehicle out of a ditch orover an embankment, or out of the sand or mud, when deeply miredtherein.

Other objects of the present invention not at this time moreparticularly enumerated will be clearly understood from the followingdetailed description of the same.

Tith the various objects of the invention in view.`the said inventionconsists, primarily. in the novel combination jack and hoist hereinaftermore fully set forth: and, the said invention consists` furthermore, inthe novel arrangements and combinations of the various devices andparts. as well as -in the details of the construction of the said parts,all of which will be more fully described in the followingspecification, and

serial no. 534,919.

then finally embodied in the clauses of the claims, which are appendedto and which form an essential part of the said specification.

The invention is clearly illustrated in the accompanying drawings, inwhich Figure l is a detail view of the combination jack and hoist. shownin a horizontal position with a flexible element extending from each endhorizontally to illustrate the use of the device when in tension inconnec tion with a vehicle for pulling the same out of a ditched ormired position.

Figure 8 is a Jface view of certain portions of the device, looking inthe direction of the arrow u in said Figure 7, with a. portion of thegear-casing shown broken away; and Figure 9 is a fragmentary view,showing the jack-feature partly in perspective and partly in section.

Figure 10 is a detail horizontal sectional .representation taken on line10-10 in said Figure 8.

Similar characters of reference are employed in all of the said abovedescribed views. to indicate corresponding parts.

Referring now to the several figures of the drawings. thereference-character 1 indicates a complete combination jack and hoist.showing one embodiment of the principles of the present invention, thesame comprising a main shell or casing consisting of a base-plate 2formed with suitably disposedA openings` as 3. Suitably mounted uponsaid base-plate 2 are two vertically disposed side-pflates 4 and 5.which are preferably slightly contracted toward each other,

as at 6 and 7, see Figures 6 of the drawings, to provide a narrowspace-portion 8 in which is vertically disposed and movably arranged arack-member 9 formed upon one edge with pawl-engaging teeth 1() and uponits upper' end with a supporting or engaging end\11, adapted to be movedagainst an axle 12 of the vehicle for lifting purposes, as indicated inFigure 4 of the drawings. A spacing-plate 13 and a gate-plate 14 arearranged between said side-plates 4 and 5, the said plate 13 and theside-plates 4 and. 5 being secured together by means of tie-bolts orscrews 15, and the said gate-plate 14 and side-plates 4 and 5 beingsecured together by means of a tie-bolt or screw 16 which also acts asa. means of pivotal connection for the said gate-plate 14, and atie-bolt or screw 17 with which a hookshaped portion 141 of t-he saidgate-plate 14 can .be brought into separable holding engagement, asf`will be evident from an inspection of saidFigure 4 of the drawings. Atthe proper locations between thel said side-plates 4 and 5 are suitablyformed guide-members or elements, as 18 'extending inwardly from anopening 20, and a guide-member 19 secured in place by a tiebolt or screw21, as shown, for properly maintaining the rack-member 9 in itsvertically movable relation between the said Side-plates 4 and 5, aswill be evident.

Extending through a suitably y,disposed perforation in the guide-memberor element 19 and through correspondingly placed perforations in thesideplates 4 and 5 is a pin or stem 22 the ends of which project beyondthe outer faces of said sidelates forv the pivotal arrangement thereon othe eyes 24 of a bail 23 to which may be attached aV chain 25, or thelike, for the purposes hereinafter more fully set forth. Pivotallymounted upon a pin or stem 26 extending across the space between thesaid side-plates 4 and 5 is a lever-receiving Socket-member 27preferably of the construction shown in Figures 3 and 4 of the drawings,for the re ception of the end-portion of an operating lever or handle28, which may be detach-- ably secured in said socket-member andmaintained in its operative relation with .said member by a removablecross-pin 29.

Pivotally mounted upon said pin or stem 26 is an upwardly extending dogor pawl 30, the said socket-member 27 being provided with another pin orstem 31 upon which is pivotally mounted a second upwardly eX- tendingpawl or dog 32, a suitably formed spring, as 33, connecting the saidpawls or dogs 3() and 32, for forcing their rackengaging end-portionsinto slidable engage` ment vwith the teeth 10 of the rack-member 9, aswill be evident. The manner of raising the rack-member 9, by means dfsaid pawls or dogs and the handle or lever 28 will be clearly understoodfrom an inspection of Figure 4 of t-he drawings, and is as follows:

Let us suppose that the various parts of the device are in the positionsindicated in Figure 4 of the drawings, and that the rack 9, with itsload 12 is to'be raised, the two pawls 30 and 32 being in the positionshown. The operator throws the plvoted latch or lever 34 in a directiontoward the rack-member 9, causing the lug 35 of said latch or lever 34to be rotated in a downward direction until its free end-portion isforcibly brought into contact with that portion of the spring 33 whereits end-portion is attac-hed tothe side of the pawl 30. By lifting thelever 28, the engaging portion of the pawl 30 remains in engagement withthe rac-k 9, the pawl 32 being moved in a downward direction asuicientdistance to permit the spring 33 to act toward and upon saidpawl 32, thus forcibly bringing its engaging end in holding engagementwith the oppositely disposed tooth of the rack 9, as will be evident.The lever 28 now being swung in a downward direction` the engagingend-portion of the pawl 32 i causes the rack 9 to be moved in an upwarddirection, the pawl 30 being forced out. of lts engagement with thetooth of the rack,

Ybut being immediately forced into active engagement with the nextsucceeding tooth by step, the operator returns the latch or lever 34 toits former position, indicated in said Figure 4 of the drawings, therebywithdrawing the lug 35 from its engagement with the spring 33. Adownward movement of the lever 28. owing to the action of the spring,forces the. pawl 32 into lifting eny gagement with the rack. and raisesthe Same slightly, so that the spring 33 now forces the other pawl 30out of its engagement with the rack, and so that as the lever 28 israised, the rack, still in engagement with the pawl 32 moves in adownward direction. while the spring 33 Aacts to force the pawl intoact-ive engagement with the succeeding and downwardly moving tooth ofthe rack, as will be clearly evident.

If desired the rack-member 9 may also be' provided in its opposite sideswith grooves or channels 37, the opposite portions- 6 and 7 of theside-plates 4 and 5 in that case being formed upon their inner faceswith correspondingly placed guide-lugs or protuberances, as 38, and asindicated more particularly in Figure 10 of the drawings.

Referring now to Figures 2,3 and 5, there is attached by means of someof the tiebolts or. screws 15, the tie-bolt or screw' 16, and thecross-pin 36, in a proper location upon the outer face of the side-plate4, a shell or casing 39 across the chamber formed by it and the saidside-plate 4, also extends the previously mentioned pin or stem 26.Disposed withinthe chamber thus formed and mounted upon a shaft 4() isaratchet-wheel 41, the said shaft 40 being rotatably journalled in abearing-portion 42 in said shell or casing 39, see Figures 2 and 3, andin correspondingly disposed bearing-portions 43 and 44, indicated indotted outline in Figure 7 of the drawings. Suitably secured upon theouter face of the sideplate 5, by means of screws 45, see Figure 8, orin any other suitable manner, is a gearcasing 46, in which is disposeda. pinion 47, the hub-portion 48 of which is suitably affixed to theYend-portion of the shaft 40 which also extends into the chamber formedby said gear-casing 46 and the outer face of the side-plate 5. The saidside-plates 4 and 5 are also provided with other bearingportions, as 49and 50, in which is journalled a shaft 51, having suitably affixedthereon by means of a set-screw 52, or in any other suitable manner, inthe space between said side-plates 4 and 5, a suitably formedchaincarrier or shea-ve 53 with which. can be brought in activeengagement the links of al chain 54, the ends of said chain, ordinarily,being movably disposed in the openings 3 of the base-plate 2,substantially as indicated in Figure 4 of the drawings. Rotary motion ofsaid shaft 51 and said chain-carrier or sheave 53 is obtained from agearwheel 55 which is suitably fixed upon that end-portion of the sha-ft51 which extends into the chamber formed by said gear-casing 46 and thesaid side-plate 5, said gear-wheel 55 being actuated from the pinion 4Twhich is in mesh therewith, in the manner and for thev purposes to bepresently set forth. Pivotally mounted upon that portion of the pre-`viously mentioned pin or stem 26 which extends across theabove-mentioned chamber formed by the shell or casing 39 and thesideplate 4 is a lever-receiving socket-member 56, similar in itsconstruction to that of the, socket-member 27, said socket-member 56being adapted to receive the end-portion of the previously mentionedoperating lever or handle 28. as indicated in Figure 5 of the.

drawings. said lever being detachably secured in said socket member 56by means of a removable cross-pin 5T, Also pivotally mounted upon saidpin or stem 26 is a downwardly extending pawl or dog` 58,` the saidsocketmember 56 being provided with another pin or stem 59 upon which ispivotally mounted a second downwardly extending pawl or dog 60, asuitably formed spring, as 61, connecting the said pawls or dogs 58( and60, for forcing their engaging end-portions into slidable and activeengagement with the teeth of the ratchet-wheel 41, in substantially thesame manner, as previously described in connection with the pawls 30 and32, and the rac-k 9. The manner of actuating the chain-carrier or`sheave and the chain from the said ratchet-wheel, when operated by thehandle or lever 28 and the dogs or pawls 58 and 60 will be clearlyunderstood from an inspection of Figures 5, 6, 7, and 8 of the drawings,and any further description of the same is therefore deemed unnecessary,and from an inspection of Figure 1, one manner of using theselast-described elements of the device as a hoisting or pulling meanswill be clearly understood.

Vvvhen the device is to be used as a jack. in order that the device maybe properly placed upon its base-plate 2, the gate-plate 14 may be movedinto its opened position, in which case the strands of chain arewithdrawn through the openings 3 in the baseplate 2, and drawn outthrough the opened portion of the main casing, but without having toremove the chain from the chain-carrier or sheave.

From the foregoing description of the present invention, it will'be seenthat I have produced a simply constructed and effectively operatingdevice, which is readily convertible into a jack for lifting purposes,or into a hoist adapted for various uses to which a hoist is applicable.

Of course. I am aware that changes may be made in the generalarrangements and combinations of the various devices ,and parts, Aaswell as in the details of the construction of the said parts, withoutdepart.
